消防服外層具有阻燃防火性能

[日期:22-08-25]

 
    消防服的服裝結構也是隨著時代的變化而發展的?,F在,消防服大致可以分為兩種結構:一種是上下分身式,另一種是上下連體式,兩者各有利弊。

 
    消防服的外層是與火和熱直接接觸的一層,也是關系到產品性能好壞的關鍵的一層,目前阻燃外層面料的加工有兩種方式:
 
    1、在纖維中加入化學添加劑或對織物進行阻燃處理,即以吸附沉積、化學鍵結合、非極性力結合或粘結作用使阻燃劑固著在織物或紗線上,以獲得阻燃效果;
 
    2、提高成纖高聚物的熱穩定性,通過提高熱裂解溫度,抑制可燃氣體的產生,增加碳化程度,使纖維不易著火燃燒,比如在大分子之間發生反應變成三維交聯立體結構等。
 
    第一種方法的發展取決于阻燃劑的發展和工藝流程的改進,第二種方法則是和一些高性能纖維的發展聯系在一起。
